UNITED STATES PATENT CFFICE REMOVABLE SASH CONSTRUCTION Harry A. Kammerer, Mount Vernon, N. Y. Application September 2, 1944, Serial No. 552,486 3 Claims. (Cl. 189-72) A further object is the provision of storm sash which may be slidably opened and closed in the same manner as windows of standard construction.

A still further object is the provision of storm sash which i fractionally engaged by its permanent holding means to hold it in any desired position, open or closed.

Still another object is the provision of storm sash which may be opened to register with the open window for the purpose of providing better ventilation.

These and other objects are attained by struc ture and mechanism illustrated in the accompanying drawing in which Figure 1 is a face view of storm sash constructed in accordance with the present specification, shown installed in a typical window frame, the view being partly broken away;

Figure 2 is a vertical section on the line 2-2 of Figure 1;

Figure 3 is a fragmentary vertical section on the line 3-3 of Figure 1;

Figure 4 is a fragmentary vertical section on the line 2-4 of Figure 1;

Figure 5 is a horizontal section on the line 5-5 of Figure 1;

Figure 6 is a horizontal of Figure 1;

Figure 7 is a fragmentary horizontal section on the line 1-1 of Figure 1;

Figure 8 is a fragmentary horizontal section on the line 8-8 of Figure 1;

Figure 9 is a perspective view of one of the side members of the permanent holding frame; and

Figure 10 is a perspective view of one of the corner members of the storm sash proper.

The permanent holding frame consists of four members: two vertical side members 20 and 28,

section on the line E$ one top cross member 22 and one bottom cross member 23.

Side members 20 and 2i are E-shaped channel bars whose outer parallel walls are cut out in part, one at its upper portion, the other at its lower portion. The purposeof these cut out portions will be disclosed shortly.

Top member 22 in cross section, appears as shown in Figur 3. It has three parallel walls; a wide outer wall 24, a medium inner wall 25, and

a. narrow outer wall 25 which are joined at right angles to the top wall or ceiling 21, said parallel walls being spaced apart the same distance as the parallel walls of the E-shaped channel bars 22 and 21. Outer wall 24 and inner wall 25 are joined at a point where the latter terminates by means of a downwardly humped web .28. The hump 29 of said web constitutes the upper bead member of the holding frame.

Bottom frame member 23 is a hollow member made, preferably, of a single piece of sheet material bent backward upon itself. It has no bottom plate to correspond to the top plate 27 of the top cross member 22. It has three parallel walls 30, 3i and 32 of which outer walls 30 and 32 register at the bottom, outer wall 30 is joined at the top to the bottom of inner wall 3| by means of a web and inner wall 3i and outer wall 32 are joined at the top by means of an upwardly humped web 33. The hump 34 of said web constitutes the lower bead member of the holding frame. A plurality of riveted spacers 35 assist in properly spacing walls 3! and 32. Walls 3! and 32 are spaced to fit into the space between adjacentparallel walls of the E-shaped channel bars I and walls 30 and 32 are spaced to fit into the space between the outer parallel walls of said channel bars.

Slidably disposed in said bottom frame member 23 is a smaller, somewhat similarly shaped member 36. A plurality of torsion springs 3? disposed between the web of frame member 23 and the corresponding web of member 36 tend to urge member 36 downwardly against window sill IS. The purpose of this arrangement will shortly become apparent. Slots 38 in member 36 accommodate spacers 35.

The four members constituting the holding frame may be made of sheet metal or of any other suitable material. They may be pressed into shape or they may be made in any other desirable way. They may be fabricated in different standard sizes or they may be cut to size on the job.

When installed, top member 22 is aiiixed, as by screws, to the top iii of the window frame, and side members 20 and 2i are aifixed in the same manner to the side posts ll of the window frame. The side members 20 and 2| may also be affixed to the top member 22 by means of screws 22a and the bottom member 23 may be afiixed to the side members by means of screw 23a.- Bottom member 23 is not afixed to the sill I9 of the window frame.

It will be noted that in each of the U shaped channels 40 and ll formed by the walls of E- shaped side member 2| is affixed, as by rivets, a U-shaped channel member 32 to whose web is amxed, as by screws, a bead 43. It will also be noted that slidably disposed in each of the U- shaped channels 44 and 45 formed by the walls of E-shaped side member 20 is a U-shaped member 48, similar, in all substantial respects, to U- shaped members 42. Torsion springs 41 tend to push members 46 out of their respective channels and cross bars 48 which are aflixed to the side member 20 and pass through apertures in the side walls of said members 46, prevent said members 46 from leaving their respective channels. Beads 49 are aflixed, as by screws, to the webs of U-shaped member 46.

The sash proper comprises side frame members 50 and 51, a top member 52, a bottom member 53 and four corner members 54. Members 50, 52 and 53 are elongated channel bars which are H-shapecl in cross section, the ends of the inner legs thereof, being bent inwardly to form a pair of flanges 55. These flanges hold, in the space that separates them, pane of glass 56. A cushion or insulating material 51', such as rubber or felt, is carried by these members 50, 5|, 52 and 53 in the space formed by the web portionsthereof, the inner leg portions and the flanges. This cushion may be made in U- shaped cross section to accommodate the edge of the glass pane. This is shown in Figures 3 and 4, for example.

It will be seen in Figure 2 that the lower sash frame has an inwardly extending flange 58 on its bottom member 53 and an outwardly extending flange 59 on its top member 52. The flange 59 assists in rendering the space between the frame of the upper sash and the frame of the lower sash weathertight. The flange 58 is a finger grip for convenience in raising or lowering the lower sash.

The corner members 54 comprises an L- shaped element 60 which is U-shaped in cross section. This element corresponds cross sectionally to cushion 51 and by the same token, to the U-shaped channel formed by the inner legs, web and flanges'of the members 50, 5!, 52 and 53, when a pane of glass projects into said channel through the space between said flanges. A plate 61 is affixed to each side of said L-shaped element, in the manner shown in Figure 10. Said plate corresponds in width to members 50, 5|, 52 and 53.

To assemble the sash, the cushions 51, L- shaped elements 60 and pane of glass are inserted into members 50, 5|, 52 and 53 in the manner indicated. Said members and the L- shaped elements are then fixed together as by means of screws.

To install the sash into the holding frame, the sash is insertedinto the vertical channels formed by the parallel walls of the E-shaped side members 20 and 2!. This is done through the cut-outportions in said side members. It will be seen in Figures 5 and 6 that the outer legs of H-shaped side members 59 and Si straddle beads 43 and 49. It will be seen in Figures 3 and 4 that the outer legs of top and bottom members 52 and 53 of the sash straddle, respectively, beads 29 and 34. Plates 6! of the corner members of the sash frame also straddle the beads.

U-shaped members 46 are brought into frictional contact with the sash frame. This permits of raising or lowering either sash to any height and leaving it there, This close contact also makes for weathertight construction. Weathertight construction is also provided by the pressure contact of the member 39 with the window sill, previously described.

Screens may be substituted for the storm sash when provided with frames which correspond to the sash frames above described.

Modifications of the invention may be incorporated therein without departing from the broad principles thereof.

I claim:
